Light weight & masculine, titanium lends itself naturally to creative design. Titanium as a material is low density & high strength. It is highly resistant to corrosion. Titanium is often used in the automotive industry, particularly in racing, due to its special endurance qualities. This cufflink is inspired by movement & interaction. The round cufflink has an inner groove that enables the small steel balls to roll around freely inside the case. The middle column has a slice of semi-precious stone set into the titanium case. The small balls are covered by a layer of clear glass.
